RELATED APPLICATION

The application is a continuation application of U.S. application Ser.No. 16/172,589, filed on Oct. 26, 2018 which claims benefit of U.S.Provisional Application No. 62/578,370, filed Oct. 27, 2017, both ofwhich are incorporated herein by reference in its entirety.

BACKGROUND Technical Field

This disclosure relates to inhibitors of one or more proteins in the Wntpathway, including inhibitors of one or more Wnt proteins, andcompositions comprising the same. More particularly, it concerns the useof an isoquinoline compound or salts or analogs thereof, in thetreatment of disorders characterized by the activation of Wnt pathwaysignaling (e.g., cancer, abnormal cellular proliferation, angiogenesis,Alzheimer's disease, lung disease, inflammation, auto-immune diseasesfibrotic disorders, cartilage (chondral) defects, and osteoarthritis),the modulation of cellular events mediated by Wnt pathway signaling, aswell as genetic diseases and neurological conditions/disorders/diseasesdue to mutations or dysregulation of the Wnt pathway and/or of one ormore of Wnt signaling components. Also provided are methods for treatingWnt-related disease states, as well as neurologicalconditions/disorders/diseases linked to overexpression of DYRK1A.

Background

The Wnt growth factor family includes more than 10 genes identified inthe mouse and at least 19 genes identified in the human. Members of theWnt family of signaling molecules mediate many short- and long-rangepatterning processes during invertebrate and vertebrate development. TheWnt signaling pathway is known for its role in the inductiveinteractions that regulate growth and differentiation, and it also playsroles in the homeostatic maintenance of post-embryonic tissue integrity.Wnt stabilizes cytoplasmic β-catenin, which stimulates the expression ofgenes including c-myc, c jun, fra-1, and cyclin Dl. In addition,misregulation of Wnt signaling can cause developmental defects and isimplicated in the genesis of several human cancers. The Wnt pathway hasalso been implicated in the maintenance of stem or progenitor cells in agrowing list of adult tissues including skin, blood, gut, prostate,muscle, and the nervous system.

Dual specificity tyrosine-phosphorylation-regulated kinase 1A is anenzyme that in humans is encoded by the DYRK1A gene. DYRK1A is a memberof the dual-specificity tyrosine phosphorylation-regulated kinase (DYRK)family. DYRK1A contains a nuclear targeting signal sequence, a proteinkinase domain, a leucine zipper motif, and a highly conservative13-consecutive-histidine repeat. It catalyzes its autophosphorylation onserine/threonine and tyrosine residues. It may play a significant rolein a signaling pathway regulating cell proliferation and may be involvedin brain development. DYRK1A is localized in the Down syndrome criticalregion of chromosome 21, and is considered to be a candidate gene forlearning defects associated with Down syndrome. DYRK1A is also expressedin adult brain neurons, indicating that DYRK1A may play a role in themature central nervous system. Thus, several lines of evidence point tosome synaptic functions of DYRK1A. For instance, it has been found thatDYRK1A phosphorylates and modulates the interaction of severalcomponents of the endocytic protein complex machinery (Dynamin 1,Amphiphysin, and Synaptojanin), suggesting a role in synaptic vesiclerecycling. In addition, a polymorphism (SNP) in DYRK1A was found to beassociated with HIV-1 replication in monocyte-derived macrophages, aswell as with progression to AIDS in two independent cohorts ofHIV-1-infected individuals.

Aqueous formulations may be aerosolized by liquidnebulizers employing either hydraulic or ultrasonic atomization or bymodified micropump systems (like the soft mist inhalers, the Aerodose®or the AERx® systems). Propellant-based systems may use suitablepressurized metered-dose inhalers (pMDIs). Dry powders may use drypowder inhaler devices (DPIs), which are capable of dispersing the drugsubstance effectively. A desired particle size and distribution may beobtained by choosing an appropriate device.

In some embodiments, the compositions of Formula (I) disclosed hereincan be administered to the ear by various methods. For example, a roundwindow catheter (e.g., U.S. Pat. Nos. 6,440,102 and 6,648,873) can beused.

Alternatively, formulations can be incorporated into a wick for usebetween the outer and middle ear (e.g., U.S. Pat. No. 6,120,484) orabsorbed to collagen sponge or other solid support (e.g., U.S. Pat. No.4,164,559).

If desired, formulations of the disclosure can be incorporated into agel formulation (e.g., U.S. Pat. Nos. 4,474,752 and 6,911,211).

In some embodiments, compounds of Formula (I) disclosed herein intendedfor delivery to the ear can be administered via an implanted pump anddelivery system through a needle directly into the middle or inner ear(cochlea) or through a cochlear implant stylet electrode channel oralternative prepared drug delivery channel such as but not limited to aneedle through temporal bone into the cochlea.

Other options include delivery via a pump through a thin film coatedonto a multichannel electrode or electrode with a specially imbeddeddrug delivery channel (pathways) carved into the thin film for thispurpose. In other embodiments the acidic or basic solid compound ofFormula (I) can be delivered from the reservoir of an external orinternal implanted pumping system.

Formulations of the disclosure also can be administered to the ear byintratympanic injection into the middle ear, inner ear, or cochlea(e.g., U.S. Pat. No. 6,377,849 and Ser. No. 11/337,815).

Intratympanic injection of therapeutic agents is the technique ofinjecting a therapeutic agent behind the tympanic membrane into themiddle and/or inner ear. In one embodiment, the formulations describedherein are administered directly onto the round window membrane viatranstympanic injection. In another embodiment, the ion channelmodulating agent auris-acceptable formulations described herein areadministered onto the round window membrane via a non-transtympanicapproach to the inner ear. In additional embodiments, the formulationdescribed herein is administered onto the round window membrane via asurgical approach to the round window membrane comprising modificationof the crista fenestrae cochleae.

In some embodiments, the compounds of Formula (I) are formulated inrectal compositions such as enemas, rectal gels, rectal foams, rectalaerosols, suppositories, jelly suppositories, or retention enemas,containing conventional suppository bases such as cocoa butter or otherglycerides, as well as synthetic polymers such as polyvinylpyrrolidone,PEG (like PEG ointments), and the like.

Suppositories for rectal administration of the drug (either as asolution, colloid, suspension or a complex) can be prepared by mixing acompound provided herein with a suitable non-irritating excipient thatis solid at ordinary temperatures but liquid at the rectal temperatureand will therefore melt or erode/dissolve in the rectum and release thecompound. Such materials include cocoa butter, glycerinated gelatin,hydrogenated vegetable oils, poloxamers, mixtures of polyethyleneglycols of various molecular weights and fatty acid esters ofpolyethylene glycol. In suppository forms of the compositions, alow-melting wax such as, but not limited to, a mixture of fatty acidglycerides, optionally in combination with cocoa butter, is firstmelted.

Solid compositions can be provided in various different types of dosageforms, depending on the physicochemical properties of the compoundprovided herein, the desired dissolution rate, cost considerations, andother criteria. In one of the embodiments, the solid composition is asingle unit. This implies that one unit dose of the compound iscomprised in a single, physically shaped solid form or article. In otherwords, the solid composition is coherent, which is in contrast to amultiple unit dosage form, in which the units are incoherent.

Examples of single units which may be used as dosage forms for the solidcomposition include tablets, such as compressed tablets, film-likeunits, foil-like units, wafers, lyophilized matrix units, and the like.In one embodiment, the solid composition is a highly porous lyophilizedform. Such lyophilizates, sometimes also called wafers or lyophilizedtablets, are particularly useful for their rapid disintegration, whichalso enables the rapid dissolution of the compound.

On the other hand, for some applications the solid composition may alsobe formed as a multiple unit dosage form as defined above. Examples ofmultiple units are powders, granules, microparticles, pellets,mini-tablets, beads, lyophilized powders, and the like. In oneembodiment, the solid composition is a lyophilized powder. Such adispersed lyophilized system comprises a multitude of powder particles,and due to the lyophilization process used in the formation of thepowder, each particle has an irregular, porous microstructure throughwhich the powder is capable of absorbing water very rapidly, resultingin quick dissolution. Effervescent compositions are also contemplated toaid the quick dispersion and absorption of the compound.

Another type of multiparticulate system which is also capable ofachieving rapid drug dissolution is that of powders, granules, orpellets from water-soluble excipients which are coated with a compoundprovided herein so that the compound is located at the outer surface ofthe individual particles. In this type of system, the water-soluble lowmolecular weight excipient may be useful for preparing the cores of suchcoated particles, which can be subsequently coated with a coatingcomposition comprising the compound and, for example, one or moreadditional excipients, such as a binder, a pore former, a saccharide, asugar alcohol, a film-forming polymer, a plasticizer, or otherexcipients used in pharmaceutical coating compositions.

Also provided herein are kits. Typically, a kit includes one or morecompounds or compositions as described herein. In certain embodiments, akit can include one or more delivery systems, e.g., for delivering oradministering a compound as provided herein, and directions for use ofthe kit (e.g., instructions for treating a patient). In anotherembodiment, the kit can include a compound or composition as describedherein and a label that indicates that the contents are to beadministered to a patient with cancer. In another embodiment, the kitcan include a compound or composition as described herein and a labelthat indicates that the contents are to be administered to a patientwith one or more of hepatocellular carcinoma, colon cancer, leukemia,lymphoma, sarcoma, ovarian cancer, diabetic retinopathy, pulmonaryfibrosis, rheumatoid arthritis, sepsis, ankylosing spondylitis,psoriasis, scleroderma, mycotic and viral infections, bone and cartilagediseases, Alzheimer's disease, lung disease, bone/osteoporotic (wrist,spine, shoulder and hip) fractures, articular cartilage (chondral)defects, degenerative disc disease (or intervertebral discdegeneration), polyposis coli, bone density and vascular defects in theeye (Osteoporosis-pseudoglioma Syndrome, OPPG), familial exudativevitreoretinopathy, retinal angiogenesis, early coronary disease,tetra-amelia, Müllerian-duct regression and virilization, SERKALsyndrome, type II diabetes, Fuhrmann syndrome,Al-Awadi/Raas-Rothschild/Schinzel phocomelia syndrome,odonto-onycho-dermal dysplasia, obesity, split-hand/foot malformation,caudal duplication, tooth agenesis, Wilms tumor, skeletal dysplasia,focal dermal hypoplasia, autosomal recessive anonychia, neural tubedefects, alpha-thalassemia (ATRX) syndrome, fragile X syndrome, ICFsyndrome, Angelman syndrome, Prader-Willi syndrome, Beckwith-WiedemannSyndrome, Norrie disease, and Rett syndrome.

Evaluation of Biological Activity

The biological activity of the compounds described herein can be testedusing any suitable assay known to those of skill in the art, see, e.g.,WO 2001/053268 and WO 2005/009997. For example, the activity of acompound may be tested using one or more of the test methods outlinedbelow.

In one example, tumor cells may be screened for Wnt independent growth.In such a method, tumor cells of interest are contacted with a compound(i.e. inhibitor) of interest, and the proliferation of the cells, e.g.by uptake of tritiated thymidine, is monitored. In some embodiments,tumor cells may be isolated from a candidate patient who has beenscreened for the presence of a cancer that is associated with a mutationin the Wnt signaling pathway. Candidate cancers include, withoutlimitation, those listed above.

In another example, one may utilize in vitro assays for Wnt biologicalactivity, e.g. stabilization of β-catenin and promoting growth of stemcells. Assays for biological activity of Wnt include stabilization ofβ-catenin, which can be measured, for example, by serial dilutions of acandidate inhibitor composition. An exemplary assay for Wnt biologicalactivity contacts a candidate inhibitor with cells containingconstitutively active Wnt/β-catenin signaling. The cells are culturedfor a period of time sufficient to stabilize β-catenin, usually at leastabout 1 hour, and lysed. The cell lysate is resolved by SDS PAGE, thentransferred to nitrocellulose and probed with antibodies specific forβ-catenin.

In a further example, the activity of a candidate compound can bemeasured in a Xenopus secondary axis bioassay (Leyns, L. et al. Cell(1997), 88(6), 747-756).

In another example, in vitro assays for DYRK1A biological activity maybe used, e.g. regulation of microtubule-associated protein tau(MAPT/Tau) phosphorylation in neuronal cell line such as the humanSH-SY5Y neuroblastoma cell line. Assays for DYRK1A-regulated level ofphosphorylation can include monitoring levels of basal pSer396 Tau,which can be measured, for example, by serial dilutions of a candidateinhibitor composition using a ten micromolar top concentration anddetected by ELISA or Western Blotting. An exemplary assay forDYRK-1A-regulated phosphorylation uses the SH-SY5Y cells cultured in a96 well plate format for a period of time sufficient to stabilizemicrotubules and Tau phosphorylation, usually at least 2 days, thentreated with a ⅓ serial dilution of compounds overnight and lysed. Thecell lysate is resolved by SDS PAGE, then transferred to nitrocelluloseand probed with an antibody specific for pSer396 Tau. Thechemiluminescence signal for HRP-linked antibodies used in westernblotting is detected using a Carestream Image Station and blotdensitometry for pSer396 and beta-actin are analyzed using ImageJ (NIH).

In a further example, the activity of a candidate compound can bemeasured by ELISA by adding the lysate mentioned above onto totalTau-coated plates and detected with a specific pSer396 antibody.Colorimetric detection of ELISA signal is performed by Cytation3 platereader (Biotek).

Example 4

The screening assay for Wnt activity is described as follows. Reportercell lines can be generated by stably transducing cancer cell lines(e.g., colon cancer) or primary cells (e.g., IEC-6 intestinal cells)with a lentiviral construct that includes a Wnt-responsive promoterdriving expression of the firefly luciferase gene.

SW480 colon carcinoma cells were transduced with a lentiviral vectorexpressing luciferase with a human Sp5 promoter consisting of a sequenceof eight TCF/LEF binding sites. SW480 cells stably expressing theSp5-Luc reporter gene and a hygromycin resistance gene were selected bytreatment with 150 μg/mL of hygromycin for 7 days. These stablytransduced SW480 cells were expanded in cell culture and used for allfurther screening activities. Each compound was dissolved in DMSO as a10 mM stock and used to prepare compound source plates. Serial dilution(1:3, 10-point dose-response curves starting from 10 μM) and compoundtransfer was performed using the ECHO 550 (Labcyte, Sunnyvale, Calif.)into 384-well white solid bottom assay plates (Greiner Bio-One) withappropriate DMSO backfill for a final DMSO concentration of 0.1%. ForSp5-Luc reporter gene assays, the cells were plated at 4,000 cells/wellin 384-well plates with a DMEM medium containing 1% fetal bovine serum,and 1% Penicillin-Streptomycin and incubated for 36 to 48 hours at 37°C. and 5% CO₂. Following incubation, 15 μl of BriteLite Plusluminescence reagent (Perkin Elmer) was added to each well of the384-well assay plates. The plates were placed on an orbital shaker for 2min and then luminescence was quantified using the Envision (PerkinElmer) plate reader. Readings were normalized to DMSO only treatedcells, and normalized activities were utilized for EC₅₀ calculationsusing the dose-response log (inhibitor) vs. response-variable slope(four parameters) nonlinear regression feature available in GraphPadPrism 5.0 (or Dotmatics). For EC₅₀ of >10 μM, the percent inhibition at10 μM is provided.

Example 5

Representative compounds were screened using the assay procedure forDYRK1A kinase activity as described below.

Each compound was dissolved in DMSO as a 10 mM stock and used to preparecompound source plates. Serial dilution (1:3, 11-point dose-responsecurves from 10 M to 0.00016 M) and compound transfer was performed usingthe ECHO 550 (Labcyte, Sunnyvale, Calif.) into 1536-well black-walledround bottom plates (Coming).

The DYRK1A kinase assay was run using the Ser/Thr 18 peptide Z-lyteassay kit according to manufacturer's instructions (Life Technologies—aDivision of Thermo-Fisher). This is a non-radioactive assay usingfluorescence resonance energy transfer (FRET) between coumarin andfluorescein to detect kinase activity which is represented as a ratio ofcoumarin emission/fluorescein emission.

Briefly, recombinant DYRK1A kinase, ATP and Ser/Thr peptide 18 wereprepared in 1× Kinase buffer to final concentrations of 0.19 μg/mL, 30μM, and 4 μM respectively. The mixture was allowed to incubate with therepresentative compounds for one hour at room temperature. All reactionswere performed in duplicate. Unphosphorylated (“0% Control”) andphosphorylated (“100% control”) forms of Ser/Thr 18 served as controlreactions. Additionally, an 11-point dose-response curve ofStaurosporine (1 uM top) was run to serve as a positive compoundcontrol.

After incubation, Development Reagent A was diluted in DevelopmentBuffer then added to the reaction and allowed to further incubate forone hour at room temperature. The plate was read at Ex 400 Em 455 todetect the coumarin signal and Ex 400 Em 520 to measure the signal(EnVision Multilabel Plate Reader, PerkinElmer).

The Emission ratio (Em) was calculated as a ratio of the coumarin (C)emission signal (at 445 nm)/Fluorescein (F) emission signal (at 520 nm).The percent phosphorylation was then calculated using the followingformula: [1−((Em ratio X F100%)−C100%)/((C0%−C100%)+(Em ratio X(F100%−F0%)))]. Dose-response curves were generated and inhibitoryconcentration (IC₅₀) values were calculated using non-linear regressioncurve fit in the Dotmatics' Studies Software (Bishops Stortford, UK).

Example 7

Representative compounds were screened using the assay procedure for tauphosphorylation activity described below.

SH-SY5Y cells (human neuroblastoma) were cultured in DMEM/F-12 mediumsupplemented with 15% FBS, Non-essential Amino Acid andPenicillin/Streptomycin. Two days before treatment, cells were seededonto 96 well plates at 5×10⁴ cells/well.

The above synthesized compounds were screened using the cell assayprocedure to assess decrease Tau phosphorylation at Ser396 (pSer396)described below.

DMSO-resuspended compounds were dispensed to 8 wells as a serialtitration from 10 μM to 4.6 nM final in medium and cells were exposedovernight (16-18 h) in a humidified incubator at 36.6c before harvest.Wells were visually checked for cell death or change in morphology andsupernatants were tested for cytotoxicity by measurement of lactatedehydrogenase release (LDH, CytoToxOne kit, Promega) if necessary. Ascontrols, commercially available DYRK1A inhibitors, Harmine and Indywhich were shown to have good DYRK1A inhibition in the kinase assay withno CDK1 activity (EC₅₀ 18 and 53 nM respectively, 6 μM for CDK1) butweak EC₅₀ in the Tau assay >10 μM.

Cells were lysed with RIPA buffer complemented with phosphatase andprotease inhibitors then lysates were spun down at 12,000 g for 10 minto remove any cellular debris. Lysates are then either directly testedfor pSer396 by ELISA (Life Technology, Kit KHB7031) or loaded on NuPageBis-Tris gels for western blot analysis. Colorimetric detection of ELISAsignal is performed by Cytation3 plate reader (Biotek) and thechemiluminescence signal for HRP-linked antibodies used in westernblotting is detected using a Carestream Image Station. The same pSer396antibody is used for detection of pTau in both assays.

Representative compounds were screened using the assay procedure toassess the effect on cell viability as described below.

SW480 colon carcinoma cells were transduced with a lentiviral vectorexpressing luciferase with a human Sp5 promoter consisting of a sequenceof eight TCF/LEF binding sites. SW480 cells stably expressing theSp5-Luc reporter gene and a hygromycin resistance gene were selected bytreatment with 150 pg/mL of hygromycin for 7 days. These stablytransduced SW480 cells were expanded in cell culture and used for allfurther screening activities. Each compound was dissolved in DMSO as a10 mM stock and used to prepare compound source plates. Serial dilution(1:3, 8-point dose-response curves from 10 μM to 0.0045 μM) and compoundtransfer was performed using the ECHO 550 (Labcyte, Sunnyvale, Calif.)into 384-well white solid bottom assay plates (Greiner Bio-One) withappropriate DMSO backfill for a final DMSO concentration of 0.1%.

For the Cell Viability Assays, the cells were plated at 2,000 cells/wellin 384-well plates with a DMEM medium containing 1% fetal bovine serum,and 1% Penicillin-Streptomycin and incubated for four days hours at 37°C. and 5% CO₂. Eight replicates of DMSO-treated cells served as controlsand cells treated with compound were performed in duplicate.

After incubation, 10 μL of CellTiter-Glo (Promega) was added to eachwell allowed to incubate for approximately 12 minutes. This reagent“results in cell lysis and generation of a luminescent signalproportional to the amount of ATP present. The amount of ATP is directlyproportional to the number of cells present in culture, in agreementwith previous reports. The CellTiter-Glo® Assay generates a “glow-type”luminescent signal, produced by the luciferase reaction (Promega.com)”.

After incubation, the plates were read at Ex 560 nm Em 590 nm (Cytation3, BioTek). Dose-response curves were generated and EC₅₀ concentrationvalues were calculated using non-linear regression curve fit in theGraphPad Prism (San Diego, Calif.) or Dotmatics' Studies Software(Bishops Stortford, UK). For EC₅₀ of >10 μM, the percent inhibition at10 μM is provided.
